Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. [10] It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway.
Nasal irrigation (also called nasal lavage, nasal toilet, or nasal douche) is a personal hygiene practice in which the nasal cavity is washed to flush out mucus and debris from the nose and sinuses, in order to enhance nasal breathing. Nasal irrigation can also refer to the use of saline nasal spray or nebulizers to moisten the mucous membranes.
It can result in a thick exudate of mucus and white blood cells caused by the swelling of the mucous membranes in the head in response to an infection.

Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever.
Screening of patients can cover presence of breathing difficulty when it is too large, because nasal airways are blocked by inflammation. [2] Some experts call pain associated with enlarged concha bullosa " will not go away with surgery when concha bullosa small in size and not blocking the airway, surgery can help for breathing improvement."
A CT scan showing evidence of the nasal cycle: the more patent airway is on the right of the image, the swollen turbinates congesting the left. The nasal cycle is the subconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals.
A woman blowing her nose (expelling mucus) into a handkerchief. Nose-blowing is the act of expelling nasal mucus by exhaling forcefully through the nose.This is usually done into a facial tissue or handkerchief, facial tissues being more hygienic as they are disposed of after each use while handkerchiefs are softer and more environmentally-friendly.
